SELF-ACTING MULE AND TWINER.

SPECIFICATION forming part of Letters Patent No.752,302, dated February 16,1904. Application filed $eptember 11, 1903. Serial No. 172,804. (No model.)

To all whmn it may concern:

Be it known that I, GEORGE EDWARD Ross, mechanical engineer, of 27 Ardwick Green north, Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Self-Acting Mules and Twiners, of which the following is a specification.

My invention relates to improvements in self-acting mules, and twiners for spinning; and the object of my improvements is to construct a carriage which will be fire-resisting and at the same time will be light and rigid. I accomplish this object by building the mulecarriage entirely of metal, the special features of my invention being that I employ sheetmetal plates secured to cast-metal stretchers or girders, and I bolt to the said stretchers both the back brackets and thefaller-brackets as Well as the side plates, to which the frames for the carriage-wheels are adjustably secured, by which means the carriage is made very strong and rigid.

In the accompanying four sheets of drawings, Figure 1 is a front elevation of part of a mule-carriage made according to my invention. Fig. 2 is a plan view of Fig. 1. Fig.

3 is a transverse vertical section of the mulecarriage on the plane of the line A B, Fig. 1,

looking toward the right. Fig. 4 is a transverse vertical section on the plane of the line C D, Fig. 1. Fig. 5 is a portion of the back elevation of the carriage drawn upon an enlarged scale, and Fig. 6 is a plan of an adjustable stretcher.

In the drawings, 1 denotes the principal metal stretchers at the base of the carriage.

'Two of the stretchers are shown being directly over the wheel-carrying frame 5. These stretchers are placed at the front and rear of the carriage and are adjustably connected together. To these stretchers are secured back brackets 2 and faller-brackets 3 as well as side brackets 4, to which the frames 5 for the carriage-wheels 6 are adjustably secured. Intermediate of each pair of stretchers 1 I prefer to employ an additional stretcher 8, and a back bracket 2 is secured to this stretcher.

' Front brackets 10 are connected to the back brackets 2 and principal stretchers 1 by adjustable stay-rods 11 and 12, and lighter brackets 13 and 9 are placed between the front brackets and. back brackets,respectively, while the principal stretchers 1 are connected to the intermediate stretchers 8 by stay-rods 1 1. To each stretcher 1 and 8 is secured a light bracket 15, which carries the lower end of one of the fallerbrackets 3, -supported above by a bolt 16, secured to one of the front brackets 10. To each principal stretcher 1 I- secure an adjustable bearing 17 for the tiri roller-shaft 18, and

as these principal stretchers carry the frame 5 for the carriage-wheels and are placed immediately over the rails 19, upon which the carriage travels, the utmost rigidity is obtained both for the tin roller-shaft and drum 20 and for the whole carriage. The bands 21 for driving the spindles 22 pass around the drum 20 and wharves 23 upon the spindles.

The carriage is completed by sheet metal plates in the following manner:

Plates 45 are supported between flanges on the back brackets 2 (see Fig. 5) and projections 2 1 cast u on them, (see Figs. 3 and 45,)

and the plates a so rest against thelight brackets '9, and being bent over at the top they can be readily lifted out and removed When necessary. Narrow sheet metal plates 50 are bolted to the back brackets 2 and 9, and these plates are preferably flanged along their front edge (see Figs. 3 and a) to support sheet-metal cover-plates 25, which rest with one edge upon the flanged portion, the front end of the plates 25 resting upon plates 26, bolted to-the front brackets 10. These plates may also be flanged at their inner edges, upon which the plates 25 may rest. In the plates 26 are fitted the bolster-bearings 40 for the spindles 22. Vertical plates 27 in front of the bolsters are secured in any convenient manner to the brackets 10 and 13 or plates 26. The front of the carriage consists of a metal plate 28, carried by hinges 29, secured to a sheet-metal plate 30, bolted to the bottom of the front brackets, which plate also carries the foot-step bearings 31 of the spindles. A vertical sheet-metal plate 32 is clamped between the feet of the principal stretchers 1 and the side brackets 4L and is also bolted to the intermediate stretchers 8 to inclose the lower front portion of the carriage,

and sheet-metal plates 33 are secured in a similar manner at the back of the carriage below the movable plates 45. The body of the carriage is completed by sheet-metal plates 34, which are bqltedvto the principal and intermediate stretchers 1 and 8, respectively.

Fig. 6 illustrates an adjustable metal stretcher made expansible as to length in two or more parts secured together by a bolt 43 and adjustable by means of a screw and locknuts 44: in order to set the carriage and for convenience of renewal in case of a breakage or accident.

By constructing the framework of .a mulecarriage with principal stretchers and bolting to such stretchers the frames for the carriagewheels, as well as the bearings for the tin roller-shaft, the back brackets, and the faller-' brackets, I am enabled to construct a strong, rigid, and light metal carriage in which the various plates of sheet metal are relieved of any undue strain.

What I claim as my invention is A self-acting mule-carriage formed entirely of metal and having in combination frames for the wheels of the carriage, principal stretchers located at the base of the carriage and being secured to said frames, intermediate stretchers between the principal stretchers, cross stay-rods connecting the principal and intermediate stretchers, back brackets extending upwardly fromand being bolted to the feet of the stretchers, adjustable front brackets, a spindle-bolster carried thereby, longitudinal stay-rods extending from the back brackets and principal stretchers, foot-step bearings carried thereby, faller-brackets carried by brackets extending forwardly from the carriage secured to the feet of the principal and intermediate stretchers and sheet-metal plates secured to the stretchers and back and front brackets for covering in the top, bottom and sides of the carriage.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GEORGE EDWARD ROSS.
